8 years and never had anything look like this... Help

[ChasidicCalvinist]

Ok. So I made an extract based IPA. It contained dried lemon and orange peel which I may have left in for...a couple weeks.

Fast forward a few months and every bottle has these white spots and the beer is totally flat.

I've been brewing for 8 years and never had anything like this happen before!

It tastes really good. Smells fine. And doesn't seem lethal. But any idea what this is?

Thanks.

The film is called a pellicle.
It indicates the presence of wild yeast and/or bacteria.
It's not dangerous to your health.
Clean your equipment thoroughly and review your process to reduce possible sources of wild microbes.

A contamination would probably not cause the beer to be flat, so that's probably a separate issue.

Troubleshooting:
Was there any kind of preservative in the fruit?
Are you keeping the bottles warm enough to carbonate?
Is it possible you forgot the priming sugar?
Can you measure the current s.g. and compare that to the s.g. when you bottled it?
Are you using some super flocculant yest strain that might not carbonate well?
